The AK6003A is a 2048-bit serial CMOS E2PROM divided into 256 registers of 8 bits each.
The AK6003A can operate full function under wide operating voltage range from 1.8V to 5.5V. The charge up circuit is integrated for high voltage generation that is used for write operation.
The AK6003A conforms to all specifications in the 2 wire protocol and is controlled by serial clock (SK) and serial data (SDA) line.
Some devices can be connected to the same bus. Each AK6003A connected to the bus is software addressable by a unique address, and can operate as either a transmitter or receiver. In addition to transmitters and receivers, devices can also be considered as masters or slaves when performing data transfers (see Table1). The master is the device which initiates a data transfers on the bus and generates the clock signals to permit that transfer. At that time, the device addressed is considered as the slave.
